My property is currently my primary residence. 4) Can I even register the property as a rental property when it has some serious code violation issues that might affect the safety of residential use: such as electrical issues, roof restoration, etc.? 

I am planning to leave my current brokerage. 

There is really no wiggle room for reconfiguring layout— and not worth simple hardware missing (in my opinion).here is a photo of the current setup.

Currently, I don't manage a STR but we do manage our LTR ourselves (I know there are plenty of differences) and as we are currently looking for a STR to invest in, we would do it ourselves.

Our current lease, based on a template, prohibits subletting, so I’m not fully aware of the pros and cons of this arrangement.

Your lender may be different and I would confirm how they will handle, since they already have one appraisal in hand.If you do go second appraisal, I would be sure to supply both the appraiser AND the lender a copy of your current lease.  

currently own a cabin worth about 400k.

I’m new to Airbnb co-hosting and I’m currently looking to co-host or virtually assist any property needing my service. 

However if you currently own, and plan on buying another primary and use the other as a rental, that's where lenders will want to verify that the new property is an upgrade from your prior property.

They have a huge service department in Boston and they track each and every repair on all appliance types and brands and keep it updated so you can get a real feel for the best choices.For those folks who have small STRs with limited space, the LG Washtower could be a good solution for installations where you can't vent the dryer and have a small area.It wouldn't be for a larger place like ours but for a 1 or 2 bedroom place, it could be a good solution if you don't currently have a washer/dryer.https://blog.yaleappliance.com/lg-compact-washtower-review?
